This is sent to adownstream logic unit (e.g. PLC, limit signal transmitter, etc.) where it is monitored to determine whether it is below or above a specified limit value.For fault monitoring, the logic unit must recognize both HI-alarms (≥ 21.0 mA) and LO-alarms (≤ 3.6 mA).Micropilot MEndress+Hauser 5Description of use as a protective systemThe Micropilot M is a "downward-looking" measuring system that functions according to the ToF method (ToF = Time of Flight). The distance from the reference point (process connection of the measuring device) to the product surface is measured. Radar impulses are emitted by an antenna, reflected off the product surface and received again by the radar system.Typical measuring arrangement:!Note!Correct installation is a prerequisite for safe operation of the device.Permitted device typesThe details pertaining to functional safety in this manual relate to the device versions listed below and are valid as of the specified software and hardware version.

All safety measures refer to this signal exclusively.The Micropilot M additionally communicates effectively via HART and contains all HART features with additional device information.The safety-related output signal is fed to a downstream logic unit, e.g. a programmable logic controller or a limit signal transmitter where it is monitored for the following:–Overshooting and/or undershooting a specified level limit.–The occurrence of a fault, e.g. error current (≤ 3.6 mA, ≥ 21.0 mA, interruption or short-circuit of the signal line).Restrictions for use in safety-related applicationsThe measuring system must be used correctly for the specific application, taking into account the medium properties and ambient conditions. Carefully follow instructions pertaining to critical process situations and installation conditions from the Operating Instructions.The specifications from the Operating Instructions (→ä7, "Supplementary device documentation") must not be exceeded.The following restriction also applies to safety-related use:–The accuracy of the 4 to 20 mA safety-related output signal is ± 10%.Micropilot MFunctional safety indicators The following tables show specific indicators for functional safety.Characteristic as per IEC 61508FMR23x with 4 to 20 mA outputSafety functions MIN MAXSIL2HFT0Device type BMode of operation Low demand modeSFF 67 % 74 %MTTR8 hRecommended time interval for proof-testing T1 1 yearλsd *2 392 FIT 87 FITλsu *2951 FIT1125 FITλdd *2541 FIT846 FITλdu *2916 FIT710 FITλtot *32800 FIT2768 FITPFD avg for T1 = 1 year *14,01 × 10-33,11 × 10-3PFD avg for T1 = 1 year *54,75 × 10-33,69 × 10-3MTBF *335 yearsSystem reaction time *4≤ 5 s*1 PFD avg*2 According to Siemens SN29500.*3 According to Siemens SN29500, including faults outside the safety function.*4 Step response time as per DIN EN 61298-2.*5 Calculated, with MTTR = 24 h, lifetime (LT) = 10 years and proof test coverage (PTC) = 98 %,Proof-test intervalEndress+Hauser9Micropilot MCharacteristic as per IEC 61508FMR24x, FMR250 with 4...20 mA outputSafety functions MIN MAXSIL2HFT0Device type BMode of operation Low demand modeSFF 68 % 75 %MTTR8 hRecommended time interval for proof-testing T1 1 yearλsd *2 356 FIT 99 FITλsu *21031 FIT1207 FITλdd *2621 FIT878 FITλdu *2903 FIT697 FITλtot *32911 FIT2881 FITPFD avg for T1 = 1 year *13,96 × 10-33,05 × 10-3PFD avg for T1 = 1 year *54,68 × 10-33,62 × 10-3MTBF *335 yearsSystem reaction time *4≤ 5 s*1 PFD avg*2 According to Siemens SN29500.*3 According to Siemens SN29500, including faults outside the safety function.*4 Step response time as per DIN EN 61298-2.*5 Calculated, with MTTR = 24 h, lifetime (LT) = 10 years and proof test coverage (PTC) = 98 %,Proof-test interval10Endress+HauserDangerous undetected failures in this scenario:An incorrect output signal that deviates from the real measured value by more than 10%, but is still in the range of 4 to 20 mA, is considered a dangerous, undetected failure.Useful lifetime of electrical components:The established failure rates of electrical components apply within the useful lifetime as per IEC 61508:2000, section 7.4.7.4. note 3.Behavior of device during operation and in case of error Behavior of device during power-upThe safe 4 to 20 mA output signal is available after 17 s after the device is switched on or when the voltage returns.Device response in the event of alarms or warningsError currentIn the event of an alarm, the output current can be configured to a value of ≤ 3.6 mA or ≥ 21.0 mA.In some cases (e.g. failure of power supply, a cable open circuit and faults in the current output itself, where the error current ≥ 21.0 mA cannot be set), output currents ≤ 3.6 mA irrespective of the configured error current can occur.For alarm monitoring, the logic unit must therefore be able to recognize both HI-alarms (≥ 21.0 mA) and LO-alarms (≤ 3.6 mA).Alarm and warning messagesAdditional information is available in the form of fault codes on the alarm and warning messages output.Installation Installation, wiring and commissioningInstallation, wiring and commissioning of the device is described in the accompanying Operating Instructions(→ä7, "Supplementary device documentation").OrientationThe permitted orientations of the device are described in the Operating Instructions.Operation Calibration of the measuring pointCalibration of the measuring point is described in the Operating Instructions.The method of device configuration!Note!Altered settings (display/FieldCare) in the "extended calibr." function group (Pos. 05) such as "offset" or"curr.turn down" (Pos. 063) in the "output" function group have an effect on the output signal.This must be taken into account when calculating the response height (see relevant Operating Instructions).We recommend that you check that the behavior of the current signal matches the expected behavior by meansof level simulation (correctness of configuration).Configuration schemata/basic calibrationThe parameters are safety-oriented with the "WHG" setting in 018 (→ information in the following table).As an alternative to activating the "WHG" setting, it is also possible to make the safety-oriented setting manually. In doing so, please observe the information in the table below.!Note!The parameters in italics are located on the service level, which can be opened with the code "300".FieldCare / Display - plain text displayDisplay VU331 Position Media type (only FMR24x, FMR250 (software version 01.05.00))001↓Tank shape *1 (FMR23x, FMR24x) or Bin type (FMR250)002↓Medium property003↓Process conditions004↓Empty calibration E005↓Full calibration F006↓Pipe diameter (for bypass / stilling well)007↓MappingSee Operating Instructions ↓Further settings: function group 05See Operating Instructions ↓Overfill protection WHG018↓On-site locking: 3 keys on the VU331 displayYes *1 For FMR 240 with wave guide antenna, stilling well must always be selected as tank shape.FieldCare /Display - plain text display Value/parameterDisplay VU331CommentSafety settings Output on ALARM Max. 110 %, 22 mA 010Parameter must be configured in this way Output echo loss ALARM 012Parameter must be configured in this way Delay time1 s014→ Note 1In safety distance SD self holding016→ Note 3!Note! 1.This parameter determines the reaction time of the device in the event of echo loss; a setting of less than 30 s is recommended.2.This parameter determines the reaction time of the device; deviating settings are possible.In case of changes in "process cond."

andmaintenance work on the device.Proof-testProof-test Check the operativeness and safety of safety functions at appropriate intervals!The operator must determine the time intervals.You can refer to the diagram "Proof-test interval" →ä9, →ä10, for this purpose.Proof-testing of the device can be performed as follows:–Approaching the level (→ test sequence A).–Removing the device and measuring a medium with comparable properties (→ test sequence B).You must also check that all cover seals and cable entries are sealing correctly.Process for proof-testing Test sequence APreparation1.Connect suitable measuring device (recommended accuracy better ±0.1 mA) to the current output.2.Determine the safety setting (level limit monitoring).Procedure for level limit monitoring1.Approach the level directly below (MAX monitoring) or directly above (MIN monitoring) the level limitto be monitored.2.Read the output current, record it and assess for accuracy.3.Approach the level directly above (MAX monitoring) or directly below (MIN monitoring) the level limitto be monitored.4.Read the output current, record it and assess for accuracy.5.The test is deemed successful if the current in step 2 does not result in activation of the safety functionbut the current in step 4 does.!Note!The proof-test is deemed to have failed if the expected current value deviates for a specific level by >±10%.For troubleshooting, → Operating Instructions (→ä7, "Supplementary device documentation"), Section 9.98% of dangerous, undetected failures are detected using this test.Test sequence BPreparation1.Prepare the test tank with the medium (dielectric constant comparable to that of the medium to bemeasured).For installation instructions, → Operating Instructions (→ä7, "Supplementary devicedocumentation"), Section 3.2.Remove the device and mount it in the test tank.3.Perform interference echo mapping if the shape and size of the test tank is different.4.Connect suitable measuring device (recommended accuracy better than ±0.1 mA) to the current output.5.Determine the safety setting (level limit monitoring).Procedure for level limit monitoring→ Test sequence A!Note!The proof-test is deemed to have failed if the expected current value deviates for a specific level by > ±10%.For troubleshooting, → Operating Instructions (→ä7, "Supplementary device documentation"), Section 9.98% of dangerous, undetected failures are detected using this test."Caution!If an interference echo mapping was performed in the test tank, a valid interference echo mapping must beperformed after the device is mounted in the original tank.!Note!If one of the test criteria from the test sequences described above is not fulfilled, the device may no longer beused as part of a safety instrumented system.The purpose of proof-testing is to detect random device failures. The impact of systematic faults on the safetyfunction is not covered by this test and must be assessed separately.Systematic faults can be caused, for example, by process material properties, operating conditions, build-up orcorrosion.RepairsRepairs Repairs on the devices must always be carried out by Endress+Hauser.Safety functions cannot be guaranteed if repairs are carried out by anybody else.Exception:The following components can be replaced by the customer if the person responsible for doing so has beentrained beforehand by Endress+Hauser:–Sensor–HF module–Electronic insert–Terminal moduleThe replaced components must be sent to Endress+Hauser for the purpose of fault analysis.Once the components have been replaced, a proof-test must be carried out as per test sequence A (→ä15)or test sequence B (→ä15).In the event of failure of a SIL-labeled Endress+Hauser device, which has been operated in a protectionfunction, the "Declaration of Contamination and Cleaning" with the corresponding note "Used as SIL device inprotection system" must be enclosed when the defective device is returned.Please refer to the Section "Return" in the Operating Instructions (→ä7, "Supplementary devicedocumentation").AppendixCommissioning or proof test ArrayprotocolExida Management SummaryEndress+Hauser2122Endress+HauserEndress+Hauser23Instruments InternationalEndress+HauserInstruments International AGKaegenstrasse 24153 ReinachSwitzerlandTel.+41 61 715 81 00Fax+41 61 715 25 00***************.comSD00327F/00/EN/13.1071125885FM+SGML 6.071125885。

LM2445operates with 80V and 12V power supplies.The part is housed in the industry standard 9-lead TO-220molded plastic power package.The circuit diagram of the LM2445is shown in Figure 1.The PNP emitter follower,Q5,provides input buffering.Q1and Q2form a fixed gain cascode amplifier with resistors R1and R2setting the gain at −20.Emitter followers Q3and Q4isolate the high output impedance of the cascode stage from the capacitance of the CRT cathode which decreases the sensitivity of the device to load capacitance.Q6provides biasing to the output emitter follower stage to reduce cross-over distortion at low signal levels.Figure 2shows a typical test circuit for evaluation of the LM2445.This circuit is designed to allow testing of the LM2445in a 50Ωenvironment without the use of an expen-sive FET probe.In this test circuit,the two 2.49k Ωresistors form a 200:1wideband,low capacitance probe when con-nected to a 50Ωcoaxial cable and a 50Ωload (such as a 50Ωoscilloscope input).The input signal from the generator is ac coupled to the base of Q5.Application HintsINTRODUCTIONNational Semiconductor (NSC)is committed to provide ap-plication information that assists our customers in obtaining the best performance possible from our products.The fol-lowing information is provided in order to support this com-mitment.The reader should be aware that the optimization of performance was done using a specific printed circuit board designed at NSC.Variations in performance can be realized due to physical changes in the printed circuit board and the application.Therefore,the designer should know that com-ponent value changes may be required in order to optimize performance in a given application.The values shown in this document can be used as a starting point for evaluation purposes.When working with high bandwidth circuits,good layout practices are also critical to achieving maximum per-formance.IMPORTANT INFORMATIONThe LM2445performance is targeted for the VGA (640x 480)to XGA (1024x 768,85Hz refresh)resolution market.The application circuits shown in this document to optimizeperformance and to protect against damage from CRT ar-cover are designed specifically for the LM2445.If another member of the LM246X family is used,please refer to its datasheet.POWER SUPPLY BYPASSSince the LM2445is a wide bandwidth amplifier,proper power supply bypassing is critical for optimum performance.Improper power supply bypassing can result in large over-shoot,ringing or oscillation.0.1µF capacitors should be connected from the supply pins,V CC and V BB ,to ground,as close to the LM2445as is practical.Additionally,a 47µF or larger electrolytic capacitor should be connected from both supply pins to ground reasonably close to the LM2445.ARC PROTECTIONDuring normal CRT operation,internal arcing may occasion-ally occur.Spark gaps,in the range of 200V,connected from the CRT cathodes to CRT ground will limit the maximum voltage,but to a value that is much higher than allowable on the LM2445.This fast,high voltage,high energy pulse can damage the LM2445output stage.The application circuit shown in Figure 9is designed to help clamp the voltage at the output of the LM2445to a safe level.The clamp diodes,D1and D2,should have a fast transient response,high peak current rating,low series impedance and low shunt capaci-tance.FDH400or equivalent diodes are recommended.Do not use 1N4148diodes for the clamp diodes.D1and D2should have short,low impedance connections to V CC and ground respectively.The cathode of D1should be located very close to a separately decoupled bypass capacitor (C3in Figure 9).The ground connection of D2and the decoupling capacitor should be very close to the LM2445ground.This will significantly reduce the high frequency voltage transients that the LM2445would be subjected to during an arcover condition.Resistor R2limits the arcover current that is seen by the diodes while R1limits the current into the LM2445as well as the voltage stress at the outputs of the device.R2should be a 1⁄2W solid carbon type resistor.R1can be a 1⁄4W metal or carbon film type resistor.Having large value resis-tors for R1and R2would be desirable,but this has the effect of increasing rise and fall times.Inductor L1is critical to reduce the initial high frequency voltage levels that the LM2445would be subjected to.The inductor will not only help protect the device but it will also help minimize rise and fall times as well as minimize EMI.For proper arc protection,it is important to not omit any of the arc protection compo-nents shown in Figure 9.L M 2445 6Application Hints(Continued)OPTIMIZING TRANSIENT RESPONSEReferring to Figure 9,there are three components (R1,R2and L1)that can be adjusted to optimize the transient re-sponse of the application circuit.Increasing the values of R1and R2will slow the circuit down while decreasing over-shoot.Increasing the value of L1will speed up the circuit as well as increase overshoot.It is very important to use induc-tors with very high self-resonant frequencies,preferably above 300MHz.Ferrite core inductors from ler Magnetics (part #78FR--k)were used for optimizing the performance of the device in the NSC application board.The values shown in Figure 11and Figure 12can be used as a good starting point for the evaluation of the ing variable resistors for R1and the parallel resistor will simplify finding the values needed for optimum performance in a given application.Once the optimum values are determined the variable resistors can be replaced with fixed values.EFFECT OF LOAD CAPACITANCEFigure 8shows the effect of increased load capacitance on the speed of the device.This demonstrates the importance of knowing the load capacitance in the application.EFFECT OF OFFSETFigure 7shows the variation in rise and fall times when the output offset of the device is varied from 40to 50V DC .The rise time shows a maximum variation relative to the center data point (45V DC )less than 5%.The fall time shows a variation of less than 8%relative to the center data point.THERMAL CONSIDERATIONSFigure 4shows the performance of the LM2445in the test circuit shown in Figure 2as a function of case temperature.The figure shows that the rise time of the LM2445increases by approximately 10%as the case temperature increases from 50˚C to 100˚C.This corresponds to a speed degrada-tion of 2%for every 10˚C rise in case temperature.The fall time increases by approximately 7%as the case tempera-ture increases from 50˚C to 100˚C.Figure 6shows the maximum power dissipation of the LM2445vs.Frequency when all three channels of the device are driving an 8pF load with a 40V p-p alternating one pixel on,one pixel off signal.The graph assumes a 72%active time (device operating at the specified frequency)which is typical in a monitor application.The other 28%of the time the device is assumed to be sitting at the black level (65V inthis case).This graph gives the designer the information needed to determine the heat sink requirement for his appli-cation.The designer should note that if the load capacitance is increased the AC component of the total power dissipation will also increase.The LM2445case temperature must be maintained below 100˚C.If the maximum expected ambient temperature inside the monitor is 70˚C and the power dissipation is 4.4W (from Figure 6,50MHz max.video frequency),then a maximum heat sink thermal resistance can be calculated:This example assumes a capacitive load of 8pF and no resistive load.TYPICAL APPLICATIONA typical application of the LM2445is shown in Figure 11and Figure ed in conjunction with an LM1267,a complete video channel from monitor input to CRT cathode can be achieved.Performance is ideal for 1024x 768resolution displays with pixel clock frequencies up to 95MHz.Figure 11and Figure 12are the schematic for the NSC demonstration board that can be used to evaluate the LM1267/2466com-bination in a monitor,and Figure 10shows the typical re-sponse at the red cathode for this application.The input video rise time is 3.2ns,and the peaking component values are those recommended in Figure 12.Table 1shows the typical cathode response of all three channels.20063710FIGURE 9.One Channel of the LM2445with the Recommended Application CircuitLM24457Application Hints(Continued)TABLE 1.LM2445Cathode Response Channel t r /OS t f /OS Red 6.3ns /7% 6.3ns /3%Green 6.1ns /6% 5.9ns /4%Blue6.5ns /3%6.4ns /2%PC BOARD LAYOUT CONSIDERATIONSFor optimum performance,an adequate ground plane,iso-lation between channels,good supply bypassing and mini-mizing unwanted feedback are necessary.Also,the length of the signal traces from the preamplifier to the LM2445and from the LM2445to the CRT cathode should be as short as possible.The following references are recommended:Ott,Henry W.,“Noise Reduction Techniques in Electronic Systems”,John Wiley &Sons,New York,1976.“Video Amplifier Design for Computer Monitors”,National Semiconductor Application Note 1013.Pease,Robert A.,“Troubleshooting Analog Circuits”,Butterworth-Heinemann,1991.Because of its high small signal bandwidth,the part may oscillate in a monitor if feedback occurs around the video channel through the chassis wiring.To prevent this,leads to the video amplifier input circuit should be shielded,and input circuit wiring should be spaced as far as possible from output circuit wiring.NSC DEMONSTRATION BOARDFigure 13shows the routing and component placement on the NSC LM1267/2466demonstration board.The schematic of the board is shown in Figure 11and Figure 12.This board provides a good example of a layout that can be used as a guide for future layouts.Note the location of the following components:•C19—V CC bypass capacitor,located very close to pin 4and ground pins•C20—V BB bypass capacitors,located close to pin 8and ground•C46,C47,C48—V CC bypass capacitors,near LM2445and V CC clamp diodes.Very important for arc protection.The routing of the LM2445outputs to the CRT is very critical to achieving optimum performance.Figure 14shows the routing and component placement from pin 1of the LM2445to the blue cathode.Note that the components are placed so that they almost line up from the output pin of the LM2445to the blue cathode pin of the CRT connector.This is done to minimize the length of the video path between these two components.Note also that D8,D9,R24and D6are placed to minimize the size of the video nodes that they are at-tached to.This minimizes parasitic capacitance in the video path and also enhances the effectiveness of the protection diodes.The anode of protection diode D8is connected directly to a section of the the ground plane that has a short and direct path to the LM2445ground pins.The cathode of D9is connected to V CC very close to decoupling capacitor C19(see Figure 14)which is connected to the same section of the ground plane as D8.The diode placement and routing is very important for minimizing the voltage stress on the LM2445during an arcover stly,notice that S3is placed very close to the blue cathode and is tied directly to CRT ground.20063716FIGURE 10.Red Cathode ResponseL M 2445 8A p p l i c a t i o n H i n t s(C o n t i n u e d )20063717F IG U R E 11.L M 126X /L M 246X D e m o n s t r a t i o n
